Archeological evidence confirms that humans used geothermal resources more than 10,000 years ago with the settlement of Paleo-Indians at hot springs locations across North America. These springs served as a resource for cooking, warmth, cleansing, and healing.
Today, the utilization of geothermal resources has expanded. While people still bathe in shallow pools heated by the earth, engineers have created technologies that allow facilities to search miles below the earth’s surface to seek out geothermal energy.
